Chet Faliszek sagt Left 4 Dead war so kaputt, das nur ein zweiter Teil das fixen konnte. (kotaku)
“Left 4 Dead was such a broken thing that nobody wanted to touch it.“
„That game iterated so quickly that if it meant breaking something horrible, where you had to load a map [two] or three times but you could playtest it today, we did it. That meant at some point, you had to pay for that debt. There was no way you were going to support mods for Left 4 Dead in the same way we did for Left 4 Dead 2 without a big reset.”
